It is not recommended to read the simplified version because the meaning of the words is different. For example, there is a distinction between "post" and "post". If you read a vernacular article, it doesn't matter whether it is simple or traditional or handwritten. But if you read old books, you'd better read old ones to understand what they mean. Especially the vernacular version, I can't understand it. For example, Li Ao called Bai Yang illiterate. Indeed, although Li Ao may be illiterate, Bai Yang is indeed full of mistakes. People who can read can't do vernacular work.
There is no difference between the printed version of Zhonghua Book Company and the acupuncture version, but it is convenient and inconvenient.
I'm not going to study it in depth, so I'd better borrow it from the library. Afraid of running away, you can also download it.
If you want to collect it, I suggest you buy an old version (see the version, printed that year) at the stall, which is what you said. At present, the fair price should be 3 yuan, and there is a lot of room for appreciation.
